This week's snow depth at Spencers Creek is 3.4cm higher than last week and one of the best depths for the site this late in the season, this century.

Since 2000, only two other years (2000 and 2017) have registered this much snow at Spencers Creek this late in September.

Further down the mountain, the snow depth at Deep Creek, located at 1,620 metres elevation, was 100.6cm. Only 2000, 2004 and 2017 had this much snow at this site, this late in the season.

Part of the reason this has been a good year for snow in the alps is the lack of rain in southeastern Australia during winter and early spring. While scarce winter rainfall has been bad news for farmers and water storages in Victoria and southern NSW, the relatively dry weather has prevented snowmelt in between cold fronts.
